OTC6779 Injector Puller for 2005-2011 GM Duramax Engines

This is a well made tool, the only thing, is I did not use it . I used a pry bar to pull all of the injectors out.

When looking at the pictures online I could not wrap my head around how this thing could possible pull an injector out of a Duramax. I decided to order it anyway because its the factory recommended tool that appears in my repair manual. I followed the detailed instructions that came with the tool and those in my factory repair manual and in no scenario can I see it providing the appropriate leverage to remove a stuck injector. I couldn't even get it to pry out an injector that I've already loosened and is just sitting in the head. All the power applied to the tool just gets transferred directly into the injector hold down with no leverage or power applied to actually pull the injector. There's another tool I found to pull straight up, but with such limited clearance in the van I'm working on and the fact that it needs to thread into the head that is currently occupied by broken off injector hold down bolts that one wont work either. Might time for me to drop the motor out for access.

Good tool

There is no information on how to use this tool. If you fit it onto the injector in the obvious way and then use it as a lever and tap on the head of the tool it lifts the injector out. I ended up using the tip of a screwdriver as a wedge under the pivot point to get extra leverage.

Works good but if the injector is really stuck you'll need to pry/wedge it out with a pry bar. This won't work. But if not that stuck it works good. Seller was good and shipped fast.

The vendor immediately dispatched my order and I'm satisfied with their business practices. Unfortunately, the diameter of the rolled bar and/or the depth that fits in the fuel injector bracket's bored retaining bolt hole is excessively too small to appropriately pry the fuel injector out. It immediately slipped out, marring the fuel injector brackets due to the incorrect fitment, but the good thing is this tool uses the correct hardness of metal alloy. I used a cheaper priced similar tool, from another manufacturer, with better results but that one bent after the forth fuel injector's extraction due to being made of a softer metal alloy.

Good tool

Broke on the first injector I used it on. Returned for a full refund with no issues. You would be better off buying a curved tip pry bar than this tool for doing lly injectors.

tried it today on a Duramax. popped the injectors out of the head with ease

As described

Instantly broke on the first time I tried to use it, can't return it now either as its been a month since I bought it!
